Wei Ling Tan –
Really like the waterproof cover and big pages—makes it much easier to jot down all the details after a long dive. The binder rings are solid, though I found it a bit bulky to carry in my backpack with other gear.

Is it possible to add extra pages or are the logbook inserts proprietary? I tend to go through log pages pretty fast during trips.
Junhao Lo –
Hi Kamal, thank you for your question! The binder rings are designed to allow you to add compatible refill pages—just make sure they match the logbook’s size and hole configuration for best fit.
